LINING GAUGE.

Application filed February 20, 1922.

To all whom it may concern:

Be it known that I, DOMENIC M. CAM- PANA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lining Gauges, of which the following is a specification.

This invention relates to a marker gauge or guide for use in connection with china and glass decoration and for other purposes of a similar nature.

The invention has for its object the provision of a gauge which shall be of improved construction, simple and economical to manufacture, and which shall be accurate and convenient in use.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawing and described in the following specification and it is more particularly pointed out in the appended claims.

In the drawing,

Fig. 1 is aplan view, showing one embodiment of the invention as it is used for lining chinaware.

Fig. 2 is a perspective view of the device shown in Fig. 1.

Fig. 3 is a view similar to F 1, showa slightly modified construction.

In china and glass decoration the designs used frequently include lines or hands parallel with the periphery of a decorated article. The ordinary compass is impractical for use in drawing lines of this kind for the reason that it is diflicult to locate the center of the article and it is practically impossible to retain a compass leg on a central point even if the point could be conveniently located. Applicants invention contemplates guiding the marker from the periphery of the article rather than from the center, thus insuring the proper location of the decoration with respect to the j ieriphery, to which the eye naturally relates the decoration rather than to the center.

In the form. of the invention shown in F l and 2, a piece of sheet metal is stamped or otherwise formed to provide spaced bars 10, connected at one end by a yoke 11 and having a cross-bar 12 adjustably mounted to slide along the bars 10. The bar 12 is bent backwardly about one of the members 10 to provide a contact piece 13 engaging the under side of themembers 10, A set-screw 14. is threaded into the bar 12 to Serial No. 537,792.

engage the upper face of the bar 10 to re tam the cross-bar in its adjusted position. It will be apparent that pressure of the screw 14 upon the bar 10 will spring the cross-bar upwardly so as to resiliently press the end of the screw against the bar 10. The ends of the bars 10 are bent to form hooks 15, which engage the periphery 16 of the article to be decorated, as shown in Fig. 1. A pencil or other suitable marker is placed at the juncture 17 of the bars 10 and 12, and by a tangential movement of the pencil the gauge is carried about the periphcry of the article, forming a line shown at 18 in Fig. 1. The cross-bar 12 is adjusted along the bars 10 to give'any spacing and any number of lines desired. The contact of the hooks 15 at spaced points on the periphcry 16 insures accurate positioning of the marker at all points about the periphery of the article. In lining the outside of glass tumblers or similar devices, the hooks 15 rest upon the rim of the tumbler with the gauge hanging down on the outside.

I here lines or hands are to be placed relatively near the center of a plate or other disk-shaped object, the tangential pressure of the pencil might tend to throw the inner end of the gauge forwardly, creating an irregular movement of the marker. To overcome this difficulty a central disk 19 may be provided, to which the inner end of the gauge is pivoted at 20. A comparatively heavy soft metal such as lead may be used to advantage for this disk. This will prevent the inner end of the gauge from moving so as to bring either of the books 15 out of contact with the periphery of the plate and yet will. permit slight movement of the pivot point 9.0 as the gauge is rotated if the pivot isnot exactly centered on the plate.

In order to adjust the length of the arms 10 of the gauge to different sized articles, the arms may be made of relatively thin, easily bent material so that when the disk 19 is placed upon the center of the article to be decorated the ends of the arms 10 may be bent over the periphery of the plate to form the hooks 15. This will properly adjust the length of the arms for a set of plates of a given. diameter, and when it is desired to use the device upon articles of a difierent diameter the ends may be bent in a diiferent place to correspond to the different sized device.

It will be apparent that the process em ployed in this invention of guiding the marker from the periphery rather than the center of the article is more convenient than guiding from the center and has the advantage of always locating the decoration in proper relation to the periphery of the article, which is the part of the object with relation to which the position of the decoration is judged by the eye of the observer.

I claim:

1. A lining device comprising a pair of spaced bars having abutment members thereon for engaging the edge of an object to receive a line, the space between said bars being open and unobstructed adjacent said abutment members, and means adjustable along said bars for positioning a marker at various distances from the edgeengaged by said abutment.

2. A lining device comprising a pair of sheet metal strips connected together at one end and havin hooks formed on the opposite end thereot, the hooked ends of said bars being unconnected to provide an open space therebetween, and means adjustable along said strips for positioning a marker at various distances from said hooks.

3. Alining device comprising a-pair of bars having hooks formed on adjacent ends thereof and having an unobstructedhopen space between said ends, a yoke connecting the opposite ends of said bars, and a crossbar adjustably mounted between said yoke and hooks for positioning a marker at various distances from said hooks.

4. A lining device comprising sheet metal strips extending parallel with one another, a yoke connecting adjacent ends of said strips to retain said strips in spaced position, hooks formed onthe opposite ends of said strips for engaging theedge of an object to be lined, a bar bent about the outer edge of one of said strips to form arms engaging opposite sides of'said strip and extending into position toengage opposite sides of the cooperating strip, and a set-screw threaded into one oi the arms of said bar and engaging the strip opposite that about which said bar is bent to retain said bar in various po sitions of adjustment along said strips.

5. Means for forming lines on an object having a curved edge, comprising contact members for engaging said edge at two spaced points thereon while leaving-theportionof said edge between said points tree, a marker guide connected with said contact members, and means at the side of said edge adjacentsaid marker guide for holdingsaid contactmembers in spaced relation with one.
